The black bear in Sichuan Zoo stands and greets like a fake bear. What skills does the black bear have?

First of all, we will introduce the carnivorous bear family, with a short snout and large and round ears. The fur on the whole body is pure black, with a crescent-shaped white spot on the chest, and the hair on the neck and shoulders is particularly long. The tail is short and small, the limbs are short and thick, the palms and soles are thick, both the front and rear limbs have 5 toes, and the claws are strong and curved. The gestation period is 6 to 7 months, and each litter usually produces 2 cubs. The cubs open their eyes one week after delivery and live independently after living with the female for 2 to 3 years. It is distributed in most areas of Northeast, Northwest, South China and Southwest China. At present, the number has dropped sharply, and it is a national second-level protected animal.

The black bear is also known as "Bear" and "Black Blind Man". It often lives in deep mountains and old forests. Due to its withdrawn temperament, it often lives alone. It can swim, climb trees, and sometimes walk upright. Movements are clumsy and slow. In winter, it moves from high mountains to low mountains, and enters hibernation period after winter. During this period, it eats nothing but sleeps, and only comes out of the hole to look for food in the following spring. Omnivorous, it feeds on plant buds, grass, tree roots, wild fruits, seeds, insects, birds, roe deer and wild boar cubs. Bear bile is a valuable medicinal material, bear paws are a delicacy on the table, and black bears are also famous ornamental animals.

In addition, let’s talk about the Asian black bear. The Asian black bear is a typical forest-dwelling animal. The northern black bear has the habit of hibernating. Establish nests in , dark ditches and shallow depressions. In autumn, they will eat a lot to prepare for hibernation. They will eat a lot of food to store fat. They will hibernate in the cave throughout the winter, not eating, and in a semi-sleep state. After hibernation, they will automatically lower their body temperature and heart rate to save the body's metabolism. He came out of the cave in March or April of the following year. The Asian black bear has a very sensitive sense of smell and hearing. It can smell the smell half a kilometer away in the wind and hear the footsteps 300 steps away. But his vision is poor, so he is known as the "black blind man". Asian black bears can walk upright like humans and sit like humans, but they move cautiously and slowly and rarely attack humans. They are generally active at night and sleep in tree holes or rock caves during the day. It is good at climbing and can go up to very tall trees to get fruits and honey; it is also good at swimming.

So it’s not surprising that black bears in zoos can stand. Real black bears can swim, climb trees, and sometimes walk upright.
